You cannot filter on a _make_timestamp column, and the following error messages appear:
UDA-SQL-0114 The cursor supplied to the operation "sqlOpenResult" is inactive
UDA-SQL-0206 The OLEDB driver returned the following value: HRESULT= DB_E_CANTCONVERTVALUE "
RSV-SRV-0025 Unable to execute this request
The solution is to apply the filter after aggregation and not before.
